See your Gyn. Bv or bacterial vaginosis is an overgrowth of bacteria that is not normally in the vagina. This abnormal bacteria causes a discharge and odor. It replaces the good bacteria or lactobacilli. It is recommended to see your gynecologist and get a firm diagnosis with a vaginal culture. If it is truly persistent BV then some options will be more prolonged treatment, taking probiotics, and other opt.
